How long in S does it take to reach its highest point?
It takes 15 seconds to reach the highest point.
What is the velocity 1 second before it reaches its highest point?
At the top, its velocity is zero. (b) What is its velocity 1 s before it reaches its highest point? One second before reaching the top, it is moving up at v = 10 m/s.
What will be speed just after 2 Second reaching the maximum height?
After another second, a total of 2 seconds, the velocity will have changed by another – 9.8 m/s so that the velocity would be (+ 19.6 m/s) + (- 9.8 m/s) = + 9.8 m/s.
How far apart are the balls at a time t after they are thrown and before they strike the ground?
t is time duration. acceleration is rate of change of velocity. t is time duration. so the balls are 28.96 meters apart at the moment when the second ball reaches 12mps.
Which three conditions must occur in order for an object to be in free fall?
Although mass has no effect on the acceleration due to gravity, there are three factors that do. They are location, location, location.
What conditions must exist for an object to be in free fall?
1 Answer. The only condition for free fall as you said is that the motion of the body should be only under the influence of gravity alone. There should not be any effect of other forces like air resistance, viscous drag etc. The condition depends on the property of the material under free fall.
What is the acceleration of a body during free fall?
A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s.
Can you survive a hundred foot fall into water?
When you fall into water from 50 or 100 feet, or above, it is like hitting concrete. The water cannot move away fast enough to let your fall be cushioned, as it is when you dive into a pool from a five-foot or ten-foot diving board. The ball might have enough momentum to break a path into the water.
